Handling redirects with Express

Join the 2022 Full-Stack Web Dev Bootcamp!

Redirects are common in Web Development. You can create a redirect using the Response.redirect() method:

res.redirect('/go-there')

This creates a 302 redirect.

A 301 redirect is made in this way:

res.redirect(301, '/go-there')

You can specify an absolute path (/go-there), an absolute url (https://anothersite.com), a relative path (go-there) or use the .. to go back one level:

res.redirect('../go-there')
res.redirect('..')

You can also redirect back to the Referer HTTP header value (defaulting to / if not set) using

res.redirect('back')
